So basically, around 2-3 weeks ago my phone's screen started acting up. Usually it'd take me two tries when turning the screen on to actually get the touch screen working. As in, I turned the screen off, the touch screen doesn't register any touches, then I shut the screen down and try again, and it sometimes works. Now, this didn't bother me - I though, maybe there's some short circuiting, it may fix itself. Fast forward 2 days later. my touch screen now needs minimum 3 tries to work, up to 9 or 10 sometimes. Note that when my touchscreen starts working, it works without a problem, all 5 fingers until the screen is shut down. Then I did something that COMPLETELY broke it - I restarted my phone. The touch screen never worked then. Like ever. I could try 100 times and it wouldn't work. I'd take out the battery, let it reset nice and **** - it doesn't work. So the next thing I did was a factory reset in recovery - the phone is restored to functionality before restarting it. Now, I didn't shut down my phone for 2 weeks, nor did it run out of battery - it's the same. Today, I've restarted it and the same problem occurred again - touchscreen completely unresponsive. So, I did the same thing as before, only this time I tested dalvik-cache and cache separately - none worked in any combination without a factory reset - at this point, I'm already certain the problem is in the software, and not the hardware. So, guess what - phone was restored to functionality with 2-3 tries after that reset. Then - an even more peculiar thing - I've enabled the touch gestures to turn on a screen. Most of the time when the screen turns on with a double tap, the password screen reacts to touch, but there are cases when I double tap, it opens, and then it doesn't work - it doesn't register touches. Most of the time, though, it doesn't even open the screen through the double tap. I've also noticed that it would sometimes happen when running - for an example, I play a lot of Cytus and Deemo - whenever there would be a break of more than 2 seconds between taps, if I didn't tap in between (so, when there are no beats to hit), it would sometimes completely ignore the next tap, as if the digitizer turned its touch detection off due to inactivity...
At this point, I have no idea what it is. I know that it's not the proximity sensor which I had originally suspected, and I know that the problem lies somewhere inside Android data folders or something a factory reset wipes. However, I have no idea where. My phone has been rooted and runs xposed, although I haven't used it since the reset - I wanted to flash a custom rom but found none other than Mstars 5.0 fresh install ROM. So, if anyone recognizes this problem, can I fix it with a new ROM flashed? Can I fix it by finding the **** that's causing this and always delete it at startup via script? Or should I just attempt to fix my phone in a repair shop?

So I have a problem with my CUBE U30GT-H. I bought it almost 3 months ago, all have worked very well, but now touch screen doesn't.
Problem occurs when I have to unlock screen, it simply doesn't work after sleep. But when I restart it works again, tablet totally works with my mice. I tried to wipe cache and reinstall firmware, but nothing changed. So i think it will be a good option if touch screen doesn't shut down when tablet put to sleep. I was searching for a touch screen config, but didn't find. I hope you can help me with problem and give some ideas.
Now I use this firmware Evolution JB 1.0.2 ( flashmyandroid.com/forum/showthread.php?1192-Release-Evolution-JB-1-0-2-27-08-2012 )
P.S. I am new on this forum so I don't know where to put this question. sorry...
Hi, I've been using ViperS 5.1.2 for some time now on my Sensation XE, and it used to work great for me. But since a few days I've got this really annoying freezing problem and I just cannot find a solution.
The touch screen just freezes without any reason, sometimes after using the phone for half an hour, but most of the time within a few seconds after unlocking the screen. When it freezes, the screen won't respond to anything, also not on the back or home button. If I use the on/off button though, the screen will respond again for one or more seconds. This happens randomly; a lot of times I can't even unlock the screen properly, and the rest of the time I only get the screen working normal for a at most 10 seconds. This way it can take a few minutes just getting to the settings menu, for example. The phone does not report any error; after using the on/off button it just goes on where it froze. Also the phone reacts to tilting the screen. Or when playing a video, this just keeps playing normally. So it seems to be purely the screen itself...
I tried a lot to figure out what could be the cause of this problem: uninstalled a lot of recently installed or updated apps, checked the amount of free space/RAM, cleared cache, Dalvik, used nandroid backups to return to a previous (in the past good working) state, tried if removing the sd card would make any difference and finally flashed the rom again. All to no avail; the problem keeps occurring. At first, after trying out a possible solution like the ones I've mentioned, it looks like this did the trick. Sometimes the phone appears to work normal for at most half an hour. But then the problem occurs again, and will at that point occur at a high frequency.
I am out of idea's right now and am getting quite desperate. I need this phone to work properly badly, as I will go on my vacation in a few days and really need to be able to use some of my apps then. So I do hope somebody can help me out here? Any help would be greatly appreciated!
Does it do this while connected to the charger or usb.??

Yes, does not make any difference. I found today that the phone is now also acting strange in clockworkmod recovery touch, that's for the first time. Can't properly use the touch screen there either any more, only with hardware buttons. So now I guess this should really be a hardware issue. Maybe the phone is just dying...
Yess its a common thing for our phone to act that way while charging.... It has somtheing to do with its poor grounding. You can find threads to help u with how to solve it.

This issue make absolutely no sense to me, and only started yesterday.
First, I am stock, unrooted, no mods, no crazy sideloaded apps, just a good old Nexus 5.
When I go to wake the phone, I have noticed that the lock screen is 100% unresponsive. I cannot enter a pattern lock. I then switched to a PIN lock, thinking maybe there was an issue with the pattern. Again, unresponsive screen. So I took my screen lock off completely, thinking there is maybe an issue with the lock screen in general. Again, even with no lock screen, I cannot swipe screens, open apps, nothing. This also includes the soft keys at the bottom.
I decide to factory reset my phone. I update only my Google apps, and again notice the same issue. The screen is totally unresponsive, but then 2 white lines will flash at the top, and the screen will work.
Once those white lines flash, the screen is completely responsive like normal, there are no other issues until the phone goes to sleep again. Sometimes the little lines flash 2 seconds after waking up, sometimes 30 seconds, sometimes I have to hard reset the phone.
I also am linking to a YouTube video that I recorded of the issue in case I am not making sense.
So can anyone explain this to me? What could cause this issue on a phone that has never been rooted or flashed or anything?
Thanks in advance for the help!

Weird. Issue. Maybe you should stick everything from your sd to your pc.
And flash a factory image from fresh install from here - https://developers.google.com/android/nexus/images - if you're lucky the drivers maybe corrupt and not the hardware

Could also be a loose connection. Maybe the flex cable to from your screen wiggled its way out a bit. I've never seen that before on any phone. I'd back everything up and flash a factory image. If the issue persists, contact Google and see if you can RMA the device.
Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.
are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?
Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.
did you try in safe mode to exclude some app causing it
Yes, I tried safe mode without success.
i would take it to Samsung repair centre if pos
Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...
i don't think it's virus. fingers crossed it's just software issue
hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!
